leetcode algorithm small problem (3)

Problem Description:

Determine if a number is palindrome

class Solution {
      public boolean isPalindrome(int x) {
           if(x<0)
                  return false;
           int rs=0;

          // Note: The following method parameters to be assigned to incoming come d

         // The following operation method is d, the value of x is not changed to facilitate the final result to x compared
           int d = x;
           the while (! D = 0) {
                  RS = RS * 10% + 10 d;
                  d / = 10;
                  }
           return (RS == X);
        }
